Scientists Discover Last Meal in 75-Year-Old Tyrannosaurus Stomach

"Scientists Discover Last Meal in 75-Year-Old Tyrannosaurus Stomach"

"Scientists have successfully revealed the last meal of a 75 million-year-old tyrannosaurus. The meal turned out to be two baby dinosaurs. This discovery provides new insights into the life of predators like the tyrannosaurus and their lives millions of years ago."

"Dr. Darla Zelenitsky from the University of Calgary stated that this finding is concrete evidence that tyrannosaurs underwent significant changes in their eating habits as they aged."

"This is a specimen of a young gorgosaurus, a close cousin of the giant tyrannosaurus rex."

"When it died, this young tyrannosaurus weighed around 330 kg, which is only about ten percent of its fully grown weight. The hind legs of two small bird-like dinosaurs, called citipes, are visible beneath its ribs. Dr. Zelenitsky, one of the lead researchers in this study published in the journal Science Advances, stated, "Now we know that this young tyrannosaurus did indeed hunt small and young dinosaurs." "

Attacking and Eating Herbivorous Dinosaurs.

"Referring to previous fossil evidence, including bite marks on larger dinosaur bones that align with tyrannosaurus teeth, scientists can envision a scene when an adult gorgosaurus weighing three tons attacked and consumed a large plant-eating dinosaur."

"Dr. Francois Therrien from the Royal Tyrell Museum of Palaeontology stated that adult tyrannosaurs tended to be relatively non-selective feeders."

"Dr. Francois Therrien stated that adult tyrannosaurs may attack large prey using the method of "biting bones and stripping flesh," he told BBC News."

"This fossil was originally discovered in the Alberta Badlands in 2009, an area that has become a focal point for dinosaur fossil hunters."

"This fossil is found in rock and has gone through a process of years to reach its current condition. Initially, there was no clear visibility of prey in its belly. However, experts at the Royal Tyrell Museum of Palaeontology in Alberta detected the presence of a small toe bone protruding from the ribs."

"Gorgosaurus is a species that is slightly smaller and older compared to T. rex. When they reach adulthood, they become 'large and muscular tyrannosaurs.'"

They undergo physical transformation as they age. Dr. Therrien explains, "Teenagers have lighter bodies, longer legs, and teeth that resemble knives." He adds, "In adult individuals, the teeth are much rounder, and we call them 'killer bananas.' The uniqueness of this specimen is physical evidence of the significant differences in feeding strategies between the juvenile and adult phases."

"They are not just monsters, but living beings that are very skilled at foraging."
